Application ined april 12, 1922.- serial No. 552,005.

To ZZ whom t may concern-f i Be it known that I, JAMES L. Buon, acitizen of the United States, residing at Sherman, in the county of Grayson and State of Texas, have invented new and useful improvements in Carpenters Tools, of which the following is a specification.

This invention relates to markingdevices, particularly to squares for use by carpenters and others, and has for its object the provision of a novel combined tri-square and marking square designed particularly for use upon siding such as is used on wooden buildings, the device being characterized by the provision of a blade of peculiar forniation which will conformingly engage against the surface of the siding so as to enable the carpenter or other operator to draw a line properly, the device being furthermore adapted for use in the usual manner for true ing up and marking corner posts.

An additional object is the provision of a tool of this character which will be very simple and inexpensive in manufacture, easy and rapid in use, eiiicient and durable in service and a general improvement in the art.

Vith the above and other` objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illus trated in the accompanying drawings in which,

Figure 1 is an elevation of my device applied to a siding,

Figure 2 is a cross section on the line 2-2 of Figure 1 showing my device in end elevation,

Figure 3 is an elevation of the vother end of my device and Figure is a top edge view.

Referring more particularly to the drawings, the letter A designates a piece of siding .such as is used in the construction of wooden buildings and B designates one of the corner posts to which the siding is secured in the ordinary manner. Tt is of course well known that in actual practice a plurality of the pieces of siding are used, but I have shown only one as it is believed that that is all which will be necessary to explain the operation of my device.

In carrying out my invention I provide a tool which consists of a handle 10 which may be constructed of wood or metal and which may be of any desired dimensions. Mortised into one end of this handle isa blade 11- which ,has its outer edge flush with the end of the handle and secured to the outer edge of the blade 11 and to the end of the handle is secured a blade 12 which has its 'opposite edges so formed as to conformingly engagey upon the siding A. The exact conguration of these edges depends of course upon the cross sectional shape of th-e particular siding to be marked though in the drawings I have shown the device as formed for engagement upon a popular type of siding. The end of the blade 12 most remote from the handle 10 is formed with lateral extensions 13 which are preferably apertured as. shown at 14 to provide means whereby the device may be suspended from a nail or the like when not in use. The end of the blade 12 at the end of the handle is formed with lateral extensions 15 designed to project over the edge of the siding and `formed with square shoulders 16 which engage the upper edge of the siding.

Secured to the other end of the handle 10 is a transverse member 17. This member 17 has both ends projecting beyond the sides of the handle 10 and these projecting ends are notched or recessed as shown at 18 for engagement upon the upper edge of the siding and align with the shoulders 16 on the projections 15 of the blade 12.

In the use of the device it will be seen that when it is desired to cut square across a piece of siding the device is placed with the handle 10 extending longitudinally and with the blade 12 disposed transversely of the siding. One recess 18 and one shoulder 16 are engaged upon the edge of the siding while one edge of the blade 12 will conformingly engage against the face of the siding. A line may thenbe drawn across the siding at the place. where it is intended to make a cut. It is likewise to be noted that the device may be used as a trissquare in the ordinary manner and that it may also be used as a scriber or a guide for marking corner posts and the like as well as performing other kindred functions in wooden building construction.

From the foregoing description and a study of the drawings it will be apparent that 'l have thus pro-vided an extremely simple and inexpensive tool which will be very effective for the purpose specified and which will produce accurate work in a very easy manner. Owing to the simplicity of the construction it is apparent that there is nothing to get `out of A,o1-der. andthe device.

should have aflong.V life and'satisiactorily perform all the functions for which it is intended. A

While I have shown and'deseribedfthe'pre rerred embodiment of the inventon,.it Visoj.

course to be understood that I reserve 'the right to make such changes ,in the form, con

claim.:

,A 4device-'o'` the kcharacter -.describ.ed oomprisingva handle., a blade secured .to one end ofnsaidfliandle; and having its end at the handle formed relatively Wide and provided Withv aligned shoulders, the opposite edges 'of saidbla'delbeing of curved shape to oon- ;tormiothe cross sectional configuration of siding, and a member carried by the other end-of the handle Iand formed with lateral extensions provided with shoulders in the same plane respectively Withsaid lii-rst named shoulders.

In testimony whereofv `aiiix Vmy signature.
